5.2 Setting scale factor compensation values
The scale factor feature allows the user to adjust the output of the powermeter.
In single-sided mode, this feature can be used to compensate for left and right leg
strength imbalance. This scale factor can also be used to modify the output of your
PRECISION powermeter to match third-party power meters or a smart trainer.
Power output can be reduced by inputting a scale factor lower than 1.000,
or increased by inputting a scale factor greater than 1.000.
For example, to increase the reported power from your single-sided powermeter
by 2%, follow these steps:
1. Spin the crank arms four times to wake your powermeter
2. Connect using the 4iiii App
3. Tap the Gear button
4. Enter 1.02 as the new scale factor and tap Done
Quick Tip: The default value for the scale factor is 1.000.
Quick Tip: The scale factor modifies the power output for each leg independently.
For example, to decrease the total power output of a dual-sided powermeter by 2%,
change both scale factors 0.980. This value is obtained by dividing the default value
of 1.000 by the percentage that you want to reduce (1.020).
